Door-bolt



UNITED STATES PATENT OEEICEc JOHN E. PARKER, OF WEST MERIDEN, CONNECTICUT. l

DOOR-BO LT.

Specification forming part of Letters Patent No. 49,296, dated August 8, 1865.

To all 'whom it may concern:

Beit known that I, JOHN EPARKER, ot' West Meriden, New Haven county, Connecticut, have invented a new and useful Improvement in Door-Bolts; and I do hereby declare t-hat the following is a full, clear, and exact description of the same7 reference being made to the annexed drawing, making,` a part of this speciiieation-that is to say:

My invention is particularly designed for the bottom of a door to effect a fastening into the floor, in which position it is desirable that the boltshould be operated by the foot,instead of the hand, both to bolt and unbolt the door. I eiect this by combining with the bolta spring, which will throw it up when not held down, and a positive stop, which will 'hold it down, but which can be removed by action either of the hand or foot.

In the annexed drawing, a represents a bolt inclosed within' an appropriate ease, b, the top being removed to exhibit the interior. From the bottom ot' the case a standard, c, rises t through a slot in the bolt d. This slot is continued above the standard, and has in it a spiral spring, f, one end of which' rests against the standard and the other presses the bolt upward. Near the lower end ofthe bolt a ratch is cut uponit, a', and into this a dog, g, takes, kept in place by a spring on the back, as seen at i. 1f, now, the foot be pressed ,upon the upper end of the bolt to throw it down against the force ot' the spring f, the bolt will be held down by the dog g, and thus cannot be pried up. A pressure ot' the foot against g will at once release the bolt and permit the spring f to throw it up.

The combination of the bolt a, spring f, and dog g, substantially in the manner and for the purposes set t'orth.

In witness whereof I have hereunto subscribed my name.
